them in each method since they are only supposed to be using their single unit of work anyways (resolving
will return the same repository anyways, but in some cases it might have been with a different UOW)
Removed SetUnitOfWork method on IRepository as this is not needed.
Removed the old implementation of RepositoryResolver and replaces it with the RepositoryInstanceResolver (but
maintained the name of RepositoryResolver)
Moved getting an IProfile to an extension method, as its not commonly used.
Removing dependencies in ContentService, so the Services and context can be moved to Core proj.
Implementing Template repository to use both filesystem and db.
Adding the PropertyEditor model as internal to slowly adopt it using a slightly different model approach then in v5.
Minor refactoring of IEntity/Entity.
